Title: Fuel injection control device for engine
IPC: F02D41/34
Filed: 1992-03-26
Abstract: PURPOSE:To reduce discharge quantity of NOx by detecting a torque fluctuation rate according to combustion of an engine, setting injection timings on the advance side and the delay side at which the detected value is a specified value, and selecting the injection timing on the side where an exhaust temperature is lower. CONSTITUTION:An engine 1 is provided with injectors 18 to inject fuel to an intake port 7. The injectors 18 are disposed for respective cylinders of the engine 1, and injection timings are set in such a way that part of injected fuel is supplied to the applicable cylinder in an intake stroke of the cylinder. The injectors 18 are thus controlled by a control unit 31 in accordance with operating conditions of the engine 1 as well as an ignition plug 27. In this case, in the control unit 31, a torque fluctuation rate according to combustion of the engine 1 is detected, and each injection timing on the advance side and the delay, side is set where the detected value is a specified value. Exhaust temperatures of the injection timings are compared with each other, and an injection timing on the lower temperature side is selected.

Title: Moistening device
Inventor: OOZEKI HIROSHI
IPC: F24F1/02
Filed: 1983-04-20
Abstract: PURPOSE:To prevent growth of mildew and to enable provision of a suitable moistening condition, by a method wherein waterdrops are continuously added on the heating top surface of a sufficiently-heated heater to moisten the waterdrops as superheated steam which is free from a moisture content. CONSTITUTION:A fire is made in a heater 1, and with a bymetal 16 elongated due to a rise in the temperature of a heating top surface 2, a plate 15 is raised. By pushing upward a valve 7 of a valve body 6 by means of a projection 22, a valve seat 10 is opened, and this causes water in the valve body 6 to flow out onto the plate 15. Water, entering through the lower part of a valve 7 into a firm adhering part A between a lower end surface 61 of a valve body and the plate 15, is immediately vaporized because of the plate 1 being heated by the heating top surface 2, and flows out to the outside of the valve body 6. Since the plate 15 is heated to a high-temperature state, steam flowing onto the plate 15 is further heated, and the steam passes through a gap 41 between a retainer member 4 of a water tank 3 and the water tank in a state of dried superheated steam which is free from a moisture content and is diffused outside the heater.

Title: Brush unit for electric rotating machine and electric rotating machine provided with brush unit
Inventor: IORI TAKAMITSU
IPC: H02K13/00
Filed: 1991-03-08
Abstract: PURPOSE:To obtain a brush unit for electric rotating machine in which a brush and a commutator can be connected with a predetermined energizing force through simple structure and operation when an electric rotating machine is assembled. CONSTITUTION:A brush 10 is mounted in a brush holder 12 while being energized by an energizing section 32. When a rotor is assembled, the brush 10 is stopped by a hook section 34 mounted on a rotor contacting section 36 which is bent by means of the rotor thus stopping the brush 10 while resisting against the energizing force exerted from the energizing section 32. When the rotor contacting section 36 is bent through assembly operation of the rotor 20, the hook section 34 is released. Consequently, the brush 10 is brought into contact with a commutator 18 with a predetermined energizing force by means of the energizing section 32.

Abstract: PURPOSE:To simultaneously obtain a high load driving capacity and a high speed by composing the titled circuit of a switching step and a push-pull type outputting step, and using a coupling capacitor for a level shift. CONSTITUTION:When VH=5V is inputted as an input, the gate potential of a MESFET3 is clamped to about 0.5V. At such a time, FET3 is turned on. At the same time, MESFET7 comes to be turned on.

Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To accurately detect the presence/absence of leakage of a bypass valve by detecting temperatures of hot water flowing upstream and downstream a connection position of the bypass pipe when the bypass valve in the bypass pipe is closed to effuse hot water, and when both temperatures are different from each other. SOLUTION: When an entrance water amount sensor 9 is on, combustion is started for hot water effusion. In a control part 20 temperatures detected by a heat exchanger temperature sensor 12 and an effluent hot water temperature sensor 13 are compared with each other, and when the temperature of the effluent hot water temperature sensor 13 is lower than that of the heat exchanger temperature sensor 12, the leakage through a bypass valve 15 is judged to be produced, and calculates the amount of the leakage. Based upon the amount of leakage, hot water effusion control is performed, previously assuming water of a flow rate corresponding to the amount of time leakage through the bypass pipe 14 flows.  Namely, a feedforward control is performed in which an opening of a gas proportional valve 8 is controlled based upon the entrance water temperature, the flow rate passing through the heat exchanger 2, and the flow rate passing through the bypass pipe 14 whereby hot water at the set temperature is effused.
